If your RV house battery dies halfway through a trip, the weekend stops with it. A lead-acid bank is heavy, slow to charge, and worn out in a couple of seasons. The Pecron WB12200 swaps all of that for a single LiFePO4 battery that lasts for years and weighs far less.
The WB12200 is a 12V 200Ah LiFePO4 battery with 2560Wh of usable storage. It drops into RV, marine, and off-grid solar systems, and it works with the Victron ecosystem for charging and monitoring.
Why choose the WB12200 lithium battery
2560Wh of LiFePO4 storage in a single 12V 200Ah battery.
Rated for 3500+ cycles to 80 percent, far beyond a lead-acid bank.
Built-in battery heating for charging in cold weather.
Victron compatible, so it fits common RV and solar charging setups.
High-current 200A output for inverters and heavy 12V loads.
Where the WB12200 fits
RV and van life: power lights, a fridge, a water pump, and an inverter as your house battery.
Marine: run electronics and trolling loads with a battery that handles deep, repeated discharge.
Off-grid solar: store solar energy in a 12V bank that pairs with standard charge controllers and inverters.
